Character mistake: After Ethel chooses the ladies who'll play instruments for their own orchestra, Fred enters the Ricardo apartment with muffs over his ears as off-key plucky piano is heard in the background, indicating Ethel is playing very badly, when in all prior episodes she played fluently for any of their show warm-up numbers.

1 character mistake in Lucy's Club Dance - chronological order
Starring: Lucille Ball, Desi Arnaz, Vivian Vance, William Frawley

Revealing mistake: At the Brown Derby, when Lucy bumps into the waiter causing him to trip and spill the tray all over William Holden, we can see that the waiter's hand is taped to the bottom of the tray for the stunt to be done efficiently. (00:15:15)
Lucy Ricardo: I made a funny?
Trivia: Fred and Ethel's bickering relationship didn't require much acting; in real life Vivian Vance and William Frawley didn't care for each other at all.
Lucy Wants New Furniture - S2-E28
Question: Lucy buys a 3 piece sofa set. One piece is an armless sofa chair. It is seen in the next episode but is never seen again. Where did it go?





Chosen answer: It's not known. She may have moved it to the spare room or it may be in a corner just off camera. There could be any number of reasons, though it probably took up too much room on the studio set, and it was removed, making it easier for the actors to move around.
